2. REVENUE

The Evergy Companies' revenues disaggregated by customer class are summarized in the following tables.

Large Load Customers

In 2026, the Evergy Companies signed electric service agreements (ESAs) with multiple large load customers to serve data centers with a projected peak steady state load of approximately 2,600 MWs. The ESAs relate to three new projects and the expansion of two separate projects previously announced. The ESAs’ terms reflect the applicable provisions of the Evergy Companies’ Large Load Power Service (LLPS) rate plans. The service of these large load customers, inclusive of an optional transitional load period not to exceed five years, has commenced or is expected to commence at dates ranging from 2026 to 2028.

Most of the Evergy Companies’ retail contracts are on demand, with customer bills that vary each month based on an approved tariff and usage. Certain commercial and industrial retail customers, primarily large load customers with expected load in excess of 75 MWs, have agreements that require a minimum amount of consideration to be paid through the end of a contract term longer than one year. The aggregate amount of the remaining contractual minimum consideration for these large load customer contracts and their weighted average remaining terms are detailed in the following table.

(a)The remaining contractual term begins with the start of service for these customers and the weighted average remaining term is based on each contract's remaining performance obligations.

(b)Remaining performance obligations are estimates based on: (i) contractual minimum amounts that typically equal 80% of customers' expected annual capacity demand and exclude potential volume-based charges such as fuel cost recoveries and (ii) current large load customer rates in effect and do not include any potential changes in these rates in future years as a result of general rate cases.
